I'm not sure if I want to stay with my stock gearing or change my gearing to a 13t/40t. Can I change the front sprocket only to see if I like it or do I need to change the front, rear sprocket and chain if I'm only experimenting?

Easy to install... If you have the proper tool

This front sprocket is a great product, very durable if you also renew your chain. Replacing your front sprocket with a bad chain will rapidly increase wear and your sprocket will not last nearly as long as if you replace your chain, this also goes hand in hand with the rear. That is why it is recommend to replace all at once. Also, I highly recommend that you buy the tool for it if the bike is a Kawasaki mini or a ktm mini. These bikes all have the clip, which if you do not have the tool to pull it off can be the biggest pain to do. Overall it is a great long lasting sprocket, but just make sure you have the tool.

Q: Which way does the Renthal 520 off road sprocket go on 2008 Suzuki rmz 250?

1 year 9 months ago

There are numbers on one side. I have the numbers and lettering facing
engine. I tried to use old sprocket as a guide but that sprocket is the same on both sides. Any help is appreciated.
Renthal 520 Off-Road Front Countershaft Sprocket
Color- Steel, Size- 13

A: Generally the writing/numbers will face out. If the sprocket has different length flanges on each side you want to make sure it goes on the same as the old sprocket or as specified in your service manual.

Q: What kind of attachment holds the front sprocket on for a 2003 cr85? and does it come with this product?

A: On the 2003 Honda CR85 the front sprocket is held to the counter shaft with a fixing plate and two bolts. The Renthal Front Sprocket does Not come with the hardware, however it can be found in our OEM section here:http://www.motosport.com/dirtbike/oem-parts/honda/2003/cr85/transmission

Q: How to reduce torque on a 2011 KTM 50sx?

2 years 11 months ago

Currently running a 10 tooth front sprocket and 42 tooth rear sprocket. Which one should I change to lower the torque on the bike. Daughter gets jerked when she gets on the gas.

A: For less bottom end power and more top end you would want to go down on the rear sprocket and/or up in the front. Remember 1 tooth in the front is equal to about 3 in the rear. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: To reduce torque (spread out the gearing) you would want to increase the size of the counter-sprocket (front sprocket connected to engine, sometimes called the drive sprocket) or decrease the rear sprocket (Large sprocket attached to wheel hub, sometimes called the driven sprocket). Keep in mind the bike will accelerate slightly slower but will also have a higher top speed. Another thing to consider is you may want to stick to changes on the sprocket, not counter-sprocket. Counter-sprocket changes are BIG changes and you can get much more gradual changes with the driven sprocket.

Something else you may want to check before changing gearing is the chain tension. You say the bike jerks when she gets on the gas, that is usually a sign of a loose or stretched chain. Be sure to adjust this to the manufacturer recommendation with is usually about 1" to 1 1/4" of free play.

Q: Would changing the sprocket size on a 07 ktm105sx help with trail riding?

2 years 11 months ago

We trail ride the most and I know a trail bike would be better overall however we like the weight and size of the 105. Would changing the sprocket size set the bike up better for trail riding? Any recommendations on a good ratio or size for front and rear. I believe the stock size is 14 in the front and 49 in the back.

A: Yes you can definitely gear your 2007 KTM105SX to work better on the trails. Going up on the rear and/or down on the front will give you more bottom end. I would recommend searching the forums to find out what gearing is working best for trails on the 105SX.

A: You can either gain acceleration or top speed, not both. 13-53 gives you a gear ratio of 4.08, going with 12-52 will give you a gear ratio of 4.33 giving you more slightly more acceleration and less top speed. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: No.

It is impossible to get both more torque AND more top end with sprocket changes. The only way to accomplish this is to change the bikes transmission gearing (1st gear ratio, 2nd gear ratio, and so on) and even with this you could only accomplish more torque on the bottom and more top end in the higher gears.

It is a give and take. With sprockets if you want more torque you sacrifice top end. If you want more top end you sacrifice torque.
